A brushless and slotless dc linear motor employing a movable set of neodymium-boron-iron type magnets is discussed in this paper. The motor can be used as a linear stepping motor as well, due to its unique topology. The flux density at specific points and the static force along the travel length of the motor were measured. A 3D finite element analysis of the flux distribution and of the static force were carried out. The dynamic characteristics such as velocity, output power and efficiency for various conditions were measured.
